Before mounting the WorldPhone antenna, look up the relative posi-
tion of the satellite,
see coverage map in chapter 1. Introduction
The antenna must be pointed at the satellite with free line of sight for
optimum receiving and transmitting conditions. The beam is perpen-
dicular to the antenna.
To find the correct
vertical angle to the
satellite, try with the
antenna adjusted to
60
°
, 30
°
or 0
°
as
indicated.
Aim the antenna/lid to-
wards the estimated
position of satellite
with
free line of
sight
.
Or make a slow
scan across the
hemisphere.
When receiving a
satellite signal, a short tone
will sound. If it is an Inmarsat
satellite, a continuous tone will sound with varying frequency.
When closing in on a satellite, turning the antenna/lid horizontally and
adjusting its vertical angle, the tone should increase in frequency.
